The boys at DWPG have the Asetek Waterchill Watercooler kit up for review.

Despite reduction in manufacturing size, the amount of power modern CPUs
require continues to increase. The end-result is that more heat is being dissipated
off smaller surfaces and this requires the CPU coolers to perform that much
better, especially when overclocking a hot AMD XP or Pentium 4. This makes water-based
cooling more and more attractive -- Enter Asetek WaterChill.
